Of course, the quality control checks for the traditional, analog processes are better defined than those for digital equipment. One of the challenges for many companies using CTP technology is how to check the quality of the resulting plates. In this case, however, how to use digital targets and measure plate performance were the challenges. Using densitometers to measure plate performance has been controversial because of the impact of the grain of the plate on the measurement. According to Ray Hep-ner, process technician of CTP production, "We learned some tough lessons about the importance of quality control checks six years ago when we began with CTP."
